About that Power

CX-Series Mono Amps are one-ohm stable, giving you even more power and wiring options for your system! This Class-D CXA900.1 supplies even more bass power than its predecessor, and it features a variable bass boost with KickEQ™, giving you as much as a 6dB of extra bump. A precise 24dB crossover and 24dB subsonic filter is included, letting you quickly tune your system to perfectionwhile providing proper protection. Use the full-range outputs to expand your system with other bass amps or a full-range amp to complete your sound. From your dash, a simple turn of the optional CXARC Remote Bass Controller (sold separately) increases your output to fit your choice of music.

CXA-Series Amplifiers accept up to 40 volts (400 watts) of speaker-level input signal. This kind of flexibility both makes line-out converters unnecessary and optimizes your sound quality at the same time!

This CXA.1 Amplifier delivers as much as 900 watts into one bass channel. See below for more details.
